NOMURA NN-20UB8 CNC LATHES

Technical Description

This CNC lathe features a maximum turning and cutting length of 7.87 inches with a maximum cutting and turning diameter and bar capacity of 0.79 inches, allowing precision machining of smaller components. The spindle bore measures 0.94 inches, compatible with a range of bar stock sizes. The primary spindle is powered by a 5 HP motor capable of speeds up to 10,000 RPM, providing high-speed rotation for efficient cutting. A secondary spindle is included, driven by a 2 HP motor with a maximum speed of 6,000 RPM, enabling multi-tasking or secondary operations without re-fixturing. The machine supports 17 tool positions, facilitating complex machining operations with multiple cutting tools and enhancing flexibility. Its live milling function permits spindle speeds up to 6,000 RPM, enabling machining centers to perform milling operations directly on the lathe. Control is managed via the Mitsubishi M70 CNC system, a high-performance controller capable of managing up to 9 axes and 11 total axes with spindles, supporting advanced functions such as high-speed error compensation, precise interpolation, and multi-part system control. The M70’s nanometer-level control increments ensure fine machining accuracy. This system’s robust capabilities include synchronous control of spindles and CNC axes, rapid acceleration and deceleration, and advanced threading features, all contributing to precise, efficient, and complex machining processes. This lathe is suitable for high-precision industrial applications demanding multi-spindle simultaneous operation and complex tool management.
